Camshaft Reluctor Wheel

WARNING: This page is about a different variant/trim than selected.

The CMP sensors are used by the ECM to monitor the position of the camshafts. The intake cam sensor wheels have 4X targets. The exhaust cam sensor wheels have a 4X target. The ECM can detect a camshaft position variance as small as 4 degrees. The variance is the difference between the actual camshaft position and the desired camshaft position.
